It seems to me that China is a synonym for everything innovative and experimental. And i don't doubt they'll be the first to adopt crypto fully
I think china isn't fully developed regarding crypto advancements, so partly that's right they're not totally focused on how crypto will become valuable in the future. US for my understanding, has been fully developed with this cryptocurrency thing, hence they're within control with regulation, and safety aspects of bitcoin, in order that it won't be abused by cyber criminals or terrorism.
